"Variant of Joash"
The name Joas is commonly a male name from the "Hebrew" origin.
Joas is a variant form of the biblical name Joash, borne in the Hebrew Bible by a king of Judah, from Hebrew yo'ash. It is the spelling used in the Latin Vulgate and in the Douay-Rheims English translation (4 Kings 11:21), and it is the form of the name used in Dutch and in French, where the child king in Racine's 1691 play Athalie is called Joas.
Joash means "Given by God.".
The pronunciation of Joas is JOH-uhs.
